Context: Ethnoracial differences may exist in exposure to trauma and posttraumatic outcomes. However, Asian Americans and Native Hawaiians/other Pacific Islanders (NHOPIs) are vastly underrepresented in research pertaining to trauma and health status sequelae.

Objective: To determine whether there are ethnoracial disparities in sexual trauma exposure and its sequelae for health and functioning among Asian Americans and NHOPIs.

Method: We examined data on sexual assault exposure from the 2006–2007 Hawaii Behavioral Risk Factor Surveillance System (H-BRFSS), which yielded a cross-sectional, adult, community-based probability sample (N=12,573). Data were collected via computer-assisted random-digit landline telephone survey. Survey response rate was found to be about 48% in 2006 and 52% in 2007. The main outcome measures were demographic information, the sexual violence module of the H-BRFSS regarding unwanted sexual experiences, and questions about health lifestyles, chronic diseases and disability, and health status and quality of life.

Conclusions: Data revealed significant ethnoracial differences between whites, Asian Americans, and NHOPIs on unwanted sexual experiences, with relative risk differing by time period. This pattern of disparity could represent early stages of a new trend in local assaultive behaviors toward NHOPIs and merits attention. Across all ethnoracial groups, a lifetime history of any unwanted sexual experience is associated with a wide range of adverse health status sequelae.
